Hey, Synthzone!!! Let's have some fun! Rank these very comparable arrangers in your own 1-2-3 order.

Korg Pa900 - Roland BK9 - Yamaha PSR-S950

They all have their pros and cons. I have played 2 of the 3 and own one of them at this time. So, at this time, this is my ranking for my needs.

1 - Roland BK-9 (76 Key... Light weight... USB Audio WAV Player... Playlist)
2 - Korg Pa900 (Great touch screen... Great drum sounds... SongBook... TC Helicon)
3 - Yamaha PSR-S950 (Great on board speakers... Great sounds... Easy interface)

All of these arrangers are close to the same price. They all have close to the same features. They are not in the same class as the Korg PA3X or the Yamaha Tyros 3, 4, or 5. So, it all comes down to your needs within this budget.

Let the fun begin!!!
